I use a Tammie DGX-500 as a controller and a Pa1x-Pro as the slave. I get an 88-key Pa1x that way. I also like the grand piano on the Yammie FAR better than the pa1x -

I'm working on a PC that will be for music only, and I'll run in on stage using my new Yammie YPG-625 as a contoller and so I'll have 3 kb's on stage as well as a PC. I'm deciding whether to go with all software synths for the PC or running a Korg M3 module.

Anyway, I've always run multiple kbd's anyway, and for my job, I never know what I'll need to play. The sounds/ styles could need to be changed on the fly, even make up new stuff on the spot.
